External Silicon Tuner Stick for Digital TV Signal Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing television tuner devices are costly and cumbersome, especially for consumers who do not use them, as they require internal installation in TVs or external hardware that is complicated to set up and takes up space, lacking a simple, unobtrusive, and low-cost solution for receiving and displaying digital terrestrial, cable, or satellite signals.
Innovation Solution
A compact television tuner device with a silicon tuner module, demodulator, and processing module, connected via HDMI or MHL connectors, that can receive digital signals and transmit them wirelessly to remote display devices, allowing for easy installation and operation without the need for internal hardware or complex setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If internal tuners are installed in electronic display devices, then digital TV signal reception capability is improved, but device cost increases
Solution Approach 1:
The patent extracts the tuner functionality from the electronic display device and places it in a separate, external device. This allows consumers who do not need digital TV reception to purchase display devices without tuners, reducing costs, while still providing the option for tuner functionality through external devices for those who need it.
Solution Approach 2:
The external tuner device is designed to be universally compatible with multiple types of electronic display devices through standard connectors (HDMI, DisplayPort, USB). This multi-functionality allows a single external tuner to serve various display devices, making the solution adaptable and cost-effective across different product lines.
2Adaptability or versatility
If external tuner hardware is used, then digital TV signal reception capability is improved, but device complexity and setup difficulty increase
Solution Approach 1:
The external tuner device automatically detects and configures itself with the connected display device, eliminating the need for complex manual setup. The device performs self-configuration through automatic connector detection and signal routing, making it as easy to set up as plugging in a USB device.
Solution Approach 2:
The patent uses standard industry connectors (HDMI, DisplayPort, USB) as intermediaries between the external tuner and display devices. These standardized interfaces simplify connectivity and automatically handle signal routing, reducing setup complexity compared to proprietary or custom connection solutions.
3Adaptability or versatility
If internal tuners are installed in electronic display devices, then digital TV signal reception capability is improved, but device volume increases
Solution Approach 1:
The tuner functionality is extracted from the display device and placed in a separate external device, allowing the display device itself to remain compact without internal tuner components. Consumers can choose to use the external tuner only when needed, keeping the main display device small and portable.
Solution Approach 2:
The patent moves the tuner functionality from the internal three-dimensional space of the display device to an external device that connects through standard interfaces. This dimensional separation allows the display device to maintain its compact form factor while still providing access to tuner functionality when required.

AI summary
Embodiments of a device for receiving a digital terrestrial, cable, or satellite television signal are described herein. For example, a silicon tuner module may be configured to receive a digital terrestrial, cable, or satellite television signal and output a digital bitstream, the digital bitstream may include audio visual content in an encoded transport stream. In a further example, a digital audio video connector may be configured to couple with a display device, the digital audio video connector may be configured to provide the digital bitstream to the display device according to a specification. In another example, a processing module may be configured to control the silicon tuner module in response to a Consumer Electronics Control command received from the display device via the digital audio video connector.
